HYDRAULIC COUPLER WITH EXCELLENT FLOW PROPERTIES
SubseaDesign’s hydraulic coupler can be pressure tested to full system working pressure against the retracted coupler without the need for an additional test cap. Due to the compact design and self sealing abilities of both sides of the coupler, ingress from sea water is confined to a minimum.
The couplers are DNVGL design approved and qualified to 3000 m (10.000ft) water depth.
The connectors can be applied on subsea wellhead connectors, riser connectors, emergency disconnect packages, quick release stab plates and emergency disconnect points.
These state of art couplers tolerate high angle interconnection and allows for both front and rear loading into hubs.
